Do you mean sort of an intrusive thought about the person? It just comes into your head without you particularly wanting it to? I have to admit I wouldn't call this OCD I don't think, but it certainly sounds like something.

I don't think it is so much intrusive, but yeah I'm not purposely trying to think these thoughts, they just come to mind.

I only posted it here, because I thought at the time it fit best, but I apologize if this thread should belong here.
